Abstract
AIM: To investigate the expression of programmed cell death 4 (Pdcd4) tumor suppressor gene in tissue specimen of renal cell carcinoma (RCC), testicular germ cell cancer and penile cancer.
METHODS: Pdcd4 expression was studied using immunohistochemistry in 188 cases of RCC and 28 controls (including 9 oncocytoma); in 74 cases of penile carcinoma (including 17 metastatic tissue samples) and 26 controls; in 11 cases of seminoma, in 14 cases of non-seminoma and 5 controls.
RESULTS: Control tissues exhibited strong core and cytoplasmatic Pdcd4 staining. In contrast, core and cytoplasmatic Pdcd4 levels were significantly decreased in cancer tissues.
CONCLUSION: Our data support a role for Pdcd4 (down-) regulation in urologic tumors. Interestingly, Pdcd4 expression seem to be a potential diagnostic marker for renal or penile tumors.
